Got a 13b ready to go just needs a rebuild, iv just remembered i bought a load of spares about the same time i picked up my ecu and charge cooler. I got east coast unbreakable side seals, hardened rx8 stationary gears, 3 window comp stationary gear bearings, set of comp corner seals, comp oil relief valve, bigger oil jets for e-shaft, comp side seal springs, comp oil seal springs and a thermal heat pellet. Its amazing what you find hidden away in your garage, forgot id even bought them.

there's a cool black with blue mazda logo clear plastic front bag for a one litre oil bottle i have with my rx8.
i keep it in the boot as it has some velcro to keep it attached to the carpet in the boot.

it'd be handy for any litre oil bottles with premix in them, as it would last you a good while.

i have been using the castrol 2T premix and i think its made a massive difference to my rx8.
better economy, better acceleration smoother etc. it feels so good to drive now, i'd love to drive it everyday
if only the petrol wasn't so expensive.

still i got 27.2mpg on a 30 mile, motorway/city drive home and i was not babying it either, a few red lines etc
